摘要

In order to study how to avoid or reduce the influence of individual subjectivity on the construction risk evaluation of tunnel, on the basis of a highway tunnel, the hierarchy of risk events was compared based on the GPR(Ground Penetrating Radar) geological predication and the traditional Expert Investigation Method that is mainly according to the geological data and engineering experience respectively, and the weight and membership of risk was built by using fuzzy synthetic evaluation model based on the comparison. Comparing the calculation conclusion with the practical engineering, and it is show that the evaluation conclusion that is being based on the GPR geological forecast is more consistent with the engineering practical situation, and the conclusion can provide effective references for the construction, and also the construction needs can be met.
